SYSTEM FOR DIFFUSION OF AIR IN snow HALLS FOR VENTILATION AND AIRCONDITIONING PURPOSES 1 Filed April 5, 1955 INVENTOR. J0s [ZOE/57' SERR/1 United States Patent Ofiiice Patented Sept. 23,- 1958 SYSTEM F ORDIFFUSION OF AIR 1N SHOW HALLS gOR O IgIIIEISTILATION AND AIRCONDITIONING Jos Llobet Serra, Barcelona, Spain Application April 5,1955, Serial No. 499,412 Claims priority, application Spain April 8,1954 1 Claim. (CI. 98-40) The present invention relates to systems forthe diffusion of air in show halls and other public rooms.

An object of the present invention is to provide an improved means forthe diffusion of air.

In accordance with the present invention, the conditioned air reachesthe public immediately after its release from conduits throughwhich itcirculates, which not only enables the effects of the air to beimmediately felt, but also requires a lower consumption of this air.

The system with which the invention is employed provides that air is.conducted through a network of conduits to a point directly below eachseat and is then taken up, in accordance with the invention, throughappropriate conduits to be released at the side of each seat through adiffuser unit provided beneath the arms.

The diffuser units for the release and distribution of conditioned airmay form a part of the arms of the seats but, in any event, is above thezone corresponding to the legs of the person seated.

In the case of more simple installations, the diffuser units may bedisposed between two consecutive arm chairs, so that the effect of onediffuser serves for conditioning the air of the zone corresponding totwo seats.

In order that the invention may be more clearly understood and readilycarried into effect, the same will next be described with reference tothe accompanying drawings in which:

Fig. 1 is a schematic sectional view of a show hall illustrating an airdiifusion system.

Fig. 2 is a schematic plan view of the same show hall.

Fig. 3 is a detail sectional view showing a partial row of arm chairswith the corresponding branched conduits for distribution of air.

Fig. 4 is a detail sectional view showing a modified arrangement of thestructure.

Fig. 5 is a schematic perspective view of a partial row of arm chairsshowing the preferred arrangement of the diffuser units.

Referring to Figs. 1 and 2, the reference number 10 illustrates a showhall comprising various rows of seats 11. The air diffusion assembly.comprises an air-intake 12, combined with a valve mechanism 13 and. afilter unit 14, an air-conditioning unit 15 of any conventional type, ablower assembly 16 and an aromatization unit 17. The conditioned airpositively moved by the blower mechanism 16, is forced through the mainconduits 18 and is distributed below the several rows of seats throughcorresponding branched conduits 19. These conduits may be arrangedeither below the floor 20 of the hall (Fig. 3) or above the same,immediately below the seats 21 extending forwardly of the back rests 22(Fig. 4). From the conduits 19, the air is taken up through verticalconduits 23 mounted on the lateral structure or side walls 24 of thechairs 22 to be released at the side of each seat through a diifuseroutlet or unit 25 provided immediately beneath the arms 26 of thedifferent .chairs. The preferred arrangement of the diffuser units isshown in Fig. 5 and is at the top front part of the side walls 24between arms 26 and seat 21. At the top of the room 10 there may bedisposed several air-outlets 27, combined or not with an exhaustermechanism.

It will be understood that the apparatus of the inven tion may be variedwithout departing from the spirit of the invention.

What is claimed is:

A floor-supported seat provided for diffusing air received from an airsource comprising a back rest, arms extending forwardly of said backrest in substantially horizontal direction, a seat coupled to the backrest and normally extending forwardly thereof at. a level lower thanthat of the arms, hollow side walls beneath said arms and on both sidesof the seat and having air diffuser outlets at their respective frontsand sides and uppermost extremities, and a conduit in each of said sidesfor coupling the outlets and source, said outlets extending between theseat and the arms.
